Detailed description of the invention
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the architecture diagram of present system.
Specific embodiment
The basic principle of data sharing method based on data sharing gateway and system of the invention is: shared side needs
The node for wanting shared data, by initiating the registration of data sharing to data sharing gateway, data sharing gateway determines institute
The registration information received, succeed in registration then data sharing node toward data sharing gateway push shared data, Data Sharing Network
It closes and shared data is stored according to source node identification；Side is quoted, that is, needs the node of other nodes sharing data, by total to data
It enjoys gateway to initiate to request the shared data of other nodes, Data Sharing Network puts the verifying of row node legitimacy, after being verified, number into
According to shared gateway according to solicited message, associated shared data is responded.
The method of the present invention specifically includes shared procedure and invocation procedure；
The shared procedure is: a certain node pushes shared data to data sharing gateway, by the data sharing gateway
Receive and store the shared data；
The invocation procedure is: a certain node shares asking for other certain node datas to data sharing gateway initiation
It asks, associated shared data is responded according to solicited message by the data sharing gateway.
It may also include registration process and legitimate verification process:
The registration process is: any node is both needed to total to the data when connecting the data sharing gateway for the first time
Enjoy gateway and initiate registration request, the data sharing gateway determines received registration information, return succeed in registration or
Failure information generates the mapping table comprising node identification information and node IP address information if succeeding in registration；
The legitimate verification process is: when any node initiates the connection request to the data sharing gateway, incite somebody to action this
The node identification information and node IP address information of node are sent to the data sharing gateway, by the data sharing gateway pair
The node carries out legitimate verification, just allows to connect after being verified.
Wherein, the Data Sharing Network off-position is in PC machine, one end access network (internet or local area network) realize with it is each
The communication of a node, for realizing the reception and push to each node data；Comprising: registration module, for receiving to any
(registration information includes unique node identification information and node IP address information to the registration information of node, for verifying node body
Part), return is succeeded in registration or failure information, if succeeding in registration, generating one includes node identification information and node IP address
The mapping table of information；
Legitimate verification module is verified, node for the identity legitimacy to any node for initiating the connection request
Identity is legal can just to put row data communication into Data Sharing Network, and not conforming to rule cannot be communicated, and close in verifying node identities
After method, legitimate verification module is that each node distributes a real-time data memory space, for storing the real-time of corresponding node
Data；When the new data for having any node arrives, former data are replaced with new number automatically by corresponding real-time data memory space
According to.
Gateway end data receiving module for that will receive the shared data come transmitted by any node, and is deposited into pair
